Ask him what may be another option for plates. Can the Prodigy system be machined away and replaced with something else? I'm told the old original Trijicon plate will work. Of course that would limit you to RMR footprint.
I'd be curious to see what two additional screws would do. Will a total of four screws hold the factory plate tight on the slide? This would seem to be a pretty straightforward solution if it would work.
